“…The detection of muscle overlying a segment of a coronary artery on MDCT is helpful for diag nosis and evaluation of MB. 15 The location of the MB in our study was most commonly in the midLAD, in concordance with previous reports. 6,8 Generally, the incidence of MB is between 0.5% and 2.5% angiographically and between 15% and 85% pathologically.…”

“…Interestingly, IVUS studies have shown that despite the strong association between MB and endothelial dysfunction, bridging segments are relatively spared from atherosclerotic plaque formation [5]. However, non-invasive imaging may detect the existence of MB even better than coronary angiography with lower risks for general patients [6,7]. Although there are now several publications on MB in patients who underwent multislice computed tomography (MSCT) of the heart, most studies had a small sample size (<300-400).…”

Background Multislice computed tomography (MSCT) can be used to detect myocardial bridging (MB) of coronary arteries. However, most published studies included small cohorts and did not collect data about predictors. We investigated prevalence and predictors of MB in an Indonesian population. Methods All patients who had MSCT at Cinere Hospital, Jakarta, Indonesia between 2006 and 2009 were included in a prospective registry. MB was defined when at least half of the coronary artery was imbedded within the myocardium with a normal epicardial course of the proximal and distal portion. Results Of the 934 patients (mean age 53 years, 37.8 % female), MB could be observed in 152 patients (16.3 %). Patients with MB were younger compared with those without MB. Coronary risk factors were not different between the two groups. Coronary calcifications and moderate to severe coronary stenoses were less prevalent in patients with MB, also after adjusting for differences in age. At the time of diagnosis, only a few patients with MB were treated with beta-blockers (35 %) or calcium channel blockers (13 %). Conclusions Prevalence of myocardial bridging as detected by MSCT is relatively high. Patients with MB were younger and had a lower prevalence of coronary sclerosis. MB could be the cause of their unexplained symptoms. Follow-up studies are necessary to assess the symptoms of these patients, their response to treatment and the incidence of (coronary) events. MSCT can be used to identify patients for potential new treatment strategies.

“…MD-CT is accepted as a reliable and sensitive tool for the diagnosis of MB and the evaluation of associated intracoronary hemodynamics. [10][11][12][13][14][15][16][17][18][19][20][21] The purpose of this article is to briefly review the literature and to analyze information concerning the prevalence, anatomic features, pathophysiologic mechanisms, clinical manifestations, and therapeutic options associated with MB. We also review the classical appearance on various imaging modalities, with a particular emphasis on MDCT coronary angiography using 64-slice MDCT and dualsource CT.…”

Myocardial bridging (MB) is a common anatomical variant rather than a congenital anomaly, and it is usually considered benign. It is generally confined to the mid-portion of the left anterior descending coronary artery. Atherosclerotic plaques are often located in the segment proximal to the bridged segment, although the tunneled segment is typically spared. Conventional coronary angiography is the gold standard for detection, but it is invasive and may not be sensitive enough to detect a thin bridge. The prevalence of MB reported in multidetector CT (MDCT) coronary angiographic series has ranged from 3.5% to 30.5% in patients with chest pain or with suspected or known coronary artery disease. Today, MDCT coronary angiography is an alternative noninvasive imaging tool that allows for easy and accurate evaluation of MB.
